Motsoako oa lik'hemik'hale oa antifreeze g11, g12, g13
Sebopeho sa motsoako
Motheo oa li-coolint (a pholileng) ke metsi a hloekisitsoeng a kopantsoeng le lino tse tahang tsa mono- le polyhydric ka likarolo tse fapaneng. Corrosion inhibitors le li-additives tsa fluorescent (dae) le tsona li hlahisoa ka concentrates. Ethylene glycol, propylene glycol kapa glycerin (ho fihlela ho 20%) e sebelisoa e le setsi sa joala.
- hlapa ka metsi
Ho sebelisoa metsi a hloekisitsoeng, a nolofalitsoeng. Ho seng joalo, sekala ka sebopeho sa li-deposit tsa carbonate le phosphate se tla theha holim'a grille ea radiator le mabota a phala.
- Ethanediol
Dihydric saturated joala, ha e na 'mala ebile ha e na monko. Mokelikeli o nang le chefo o mafura a nang le ntlha ea leqhoa ea -12 °C. E na le lintho tse tlotsang. Ho fumana antifreeze e lokiselitsoeng, ho sebelisoa motsoako oa 75% ethylene glycol le 25% ea metsi. Likahare tsa li-additives li hlokomolohuoa (ka tlase ho 1%).
- Propanediol
Hape ke propylene glycol - homologue e haufi ka ho fetisisa ea ethanediol e nang le liathomo tse tharo tsa carbon ka ketane. Seeledi se senang chefo se nang le tatso e monate e nyane. Antifreeze ea khoebo e ka ba le 25%, 50%, kapa 75% propylene glycol. Ka lebaka la litšenyehelo tse phahameng, e sebelisoa hangata ho feta ethanediol.
Mefuta ea li-additives
Ethylene glycol antifreeze bakeng sa likoloi e na le oxidize nakong ea ts'ebetso ea nako e telele 'me e theha glycolic, hangata e leng formic acid. Kahoo, tikoloho ea acidic e sa rateheng bakeng sa tšepe e bōptjoa. Ho kenyelletsa mekhoa ea oxidative, li-anti-corrosion additives li kenngoa ka har'a pholiso.
- Li-inorganic corrosion inhibitors
Kapa "setso" - metsoako e thehiloeng ho silicates, nitrate, nitrite kapa letsoai la phosphate. Li-additives tse joalo li sebetsa e le sesebelisoa sa alkaline 'me li etsa filimi e sa sebetseng holim'a tšepe, e thibelang liphello tsa joala le lihlahisoa tsa eona tsa oxidation. Li-antifreeze tse nang le inorganic inhibitors li tšoailoe ka lebitso la "G11" mme li na le 'mala o motala kapa o moputsoa. Li-inorganic inhibitors li kenyelelitsoe sebopehong sa antifreeze, se pholisang se hlahisoang lapeng. Bophelo ba tšebeletso bo lekanyelitsoe ho lilemo tse 2.
- Li-inhibitors tsa Organic
Ka lebaka la mohloli o lekanyelitsoeng oa li-inorganic inhibitors, li-analogues tse sa rateheng tikolohong le lik'hemik'hale tse hanyetsanang le lik'hemik'hale, li-carboxylates, li entsoe. Matsoai a li-carboxylic acid ha a sireletse sebaka sohle se sebetsang, empa ke feela setsi sa kutu, se koahelang sebaka seo ka filimi e tšesaane. E khethiloe e le "G12". Bophelo ba tšebeletso - ho fihlela lilemo tse 5. Li khubelu kapa li pinki ka 'mala.
- kopanetsoe
Maemong a mang, "li-organics" li kopantsoe le "inorganics" ho fumana li-antifreeze tse nyalisitsoeng. Mokelikeli ke motsoako oa li-carboxylates le letsoai la inorganic. Nako ea tšebeliso ha e fete lilemo tse 3. Mmala o motala.
- Lobrid
Sebopeho sa concentrate tabeng e joalo se kenyelletsa li-reagents tsa diminerale le li-additives tsa organic anti-corrosion. Ea pele e etsa nanofilm holim'a holim'a tšepe eohle, ea morao-rao e sireletsa libaka tse senyehileng. Nako ea tšebeliso e fihla lilemo tse 20.
fihlela qeto e
Sepholisa se theola ntlha ea leqhoa ea metsi 'me se fokotsa coefficient ea katoloso. Motsoako oa lik'hemik'hale oa antifreeze ke motsoako oa metsi a silafalitsoeng ka lino tse tahang, hape o kenyelletsa li-corrosion inhibitors le dae.
